L.J. Wing IFB horizontal tube integral face and bypass coils offer the most effective preheat system ever developed. The IFB coil controls air temperature while full steam pressure or water flow is maintained in the coil at all times. The preset discharge air temperature is held constant regardless of variations in the inlet air temperature. Ideally suited for make-up air, combustion air make-up, penthouse units, air conditioning preheat and heating and ventilating units. Performance can be calculated by using the L.J. Wing specifier program.
